Texas Instruments MSP430G2213IRHB32R

Overview

MSP430G2213IRHB32R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 2 kB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, an on-chip comparator (Comp_A+), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and up to 24 capacitive-touch-enabled I/O pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2213IRHB32R datasheet, MSP430G2213IRHB32R pinout, MSP430G2213IRHB32R application, or MSP430G2213IRHB32R equivalent, key selection criteria include its 2 kB flash size, absence of ADC10 (distinguishing it from G2x53 variants), QFN-32 package with AVCC/DVCC separation, Spy-Bi-Wire debug interface, and support for five low-power modes including sub-1 µs wake-up from LPM3.

Technical Context

The MSP430G2213IRHB32R implements a 16-bit CPU with seven addressing modes and 51 instructions, paired with a basic clock module supporting DCO (calibrated up to 16 MHz), 32-kHz crystal (XIN/XOUT), and internal LF oscillator. Its peripheral set excludes ADC10 but includes Comp_A+ with eight input channels and slope A/D capability, dual USCI modules for flexible serial communication, and two independent Timer_A3 modules for timing, capture, and PWM generation.

Power management is central: five software-selectable low-power modes (LPM0–LPM4) enable current draw as low as 0.1 µA in off mode with RAM retention and 0.5 µA in standby mode, while ultra-fast wake-up (<1 µs from LPM3) supports event-driven operation in energy-constrained systems without sacrificing responsiveness.

FAQ

Does the MSP430G2213IRHB32R include an analog-to-digital converter (ADC)?

No, the MSP430G2213IRHB32R does not include the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit ADC found in G2x53 variants like MSP430G2253IRHB32. Instead, it provides Comp_A+ for analog threshold detection and slope A/D conversion. This makes MSP430G2213IRHB32R appropriate for applications relying on comparator-based decisions rather than digitized analog values.

What is the maximum operating frequency of the MSP430G2213IRHB32R?

The MSP430G2213IRHB32R supports a maximum system clock (MCLK) frequency of 16 MHz, achieved via its digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. The DCO stabilizes in less than 1 µs, enabling rapid transitions from low-power modes to full-speed operation - a key enabler for duty-cycled sensor applications.

How many I/O pins does the MSP430G2213IRHB32R support, and are they all capacitive-touch capable?

The MSP430G2213IRHB32R supports up to 24 capacitive-touch-enabled I/O pins across Ports P1, P2, and P3. All I/O bits are individually configurable with programmable pullup/pulldown resistors and pin oscillator enable bits. This allows full implementation of touch buttons, sliders, and wheels without external components - confirmed in the device family user's guide SLAU144 and datasheet SLAS735J.

What debug interface does the MSP430G2213IRHB32R use, and what pins are required?

The MSP430G2213IRHB32R uses the Spy-Bi-Wire (SBW) interface, a 2-wire variant of JTAG. It requires only two pins: RST/NMI/SBWTDIO (pin 23) and TEST/SBWTCK (pin 24). This reduces PCB routing complexity and eliminates the need for a full 4-wire JTAG header, making it ideal for space-constrained designs while retaining full flash programming and real-time debugging capability.

Is the MSP430G2213IRHB32R pin-compatible with other devices in the MSP430G2x13 family?

Yes, the MSP430G2213IRHB32R is pin-compatible with all other MSP430G2x13 devices offered in the 32-pin QFN (RHB) package, including MSP430G2113IRHB32, MSP430G2313IRHB32, and MSP430G2413IRHB32. They share identical pinouts, electrical characteristics, and package dimensions, allowing hardware reuse across different flash/RAM configurations within the same family.
